This invention relates to cigar machines, and more particularly to suchmachines having a rolling table and an apron lying thereupon and beingadapted to wind a tobacco filler into a tobacco leaf or binder, as inthe operation of cigar bunching machines. In such machines the bunchrolling apron is operated by a bunch roller moving transversely into aposition beyond the front end of the table, so as to cause part of theapron also to project beyond said front end of the table and eject thecigar or bunch. However, if a finished without injuring the cigarsticking to the apron.

Another object of the invention is to provide means for protecting theapron from injuries otherwise likely to be caused when using cigarcutting means in the removal of the above-mentioned drawback.

In the drawings- Fig. 1 is an elevational side view of one embodiment ofthe machine including the subject matter of the invention;

Fig. 2 is an elevational front view of the machine; and

Fig. 3 is an elevational side view on an enlarged scale of part of themachine.

A rolling table 2 is mounted on the machine frame I and supports a cigarrolling apron 3 the front end of which is secured to the machine framebelow the front end 4 of the rolling table. A bunch roller 5 is movabletransversely over the rolling table and actuates the apron 3 to Wind atobacco filler into a pasted binder placed in an outspread conditionupon the apron. The Wound product, viz., the cigar A, has to be expelledby the apron at the front end 4 of the rolling table, so as by acontinuously revolving shaft I I. A cam disc I2 is secured to the shaftII and reciprocates a rod I3 which is pivotally connected to a lever armI 4 which is pivotally journalled on a shaft I5. The upper, forked endof the lever arm I4 carries the bunch roller 5. Another cam disc IBsecured to the shaft I I and operates a lever I 1 to which is pivotedone end'of a link rod I8 the other end of which is pivoted to ashortlever I9. The lever I9 is secured to a shaft 2 I' which isrotatably journalled in the brackets 26. Two other levers 22 are securedto the shaft 2|, and each of them carries one of the cigar carriers 8,adjustably connected to them. To each of the carriers 8 is secured arounded nose 23 which projects upwardly beyond the cutter edges. Whenelevating the carriers 8 the noses 23 will hit the lower side of theapron 3 between the roller 5 and the front end of the rolling table 2,so that the cutter edges I will never engage the apron. Thus thecarriers 8 are first moved into the position close beneath the apron 3,as shown in Fig. 3. Thereafter, the bunch roller 5 is retracted, and bymeans of the rod 25 it retracts the forwardly projecting part of theapron 3, so that the bunch retained by the noses 23 is swept off theapron and drops into the receiver 6. Thereafter, the carriers 8 are,elevated further and swung forwards, whereby the I cigar is transferredto the cutters 9 and further to drop into a receiver 6 when the bunchroller 5 has reached its foremost position, as shown in Fig. 3. Transfermeans including a pair of carriers 8, having two sharp cutting edges 1,is positioned substantially below the receiver '5. The carriers 8 aremovable upwards to transfer the expelled cigar from the receiver 6 to areceptacle III. The ends of the cigar are cut in transit by the coactionof the cutter edges I of the carrier 8 and stationary cutters 9 whichare laterally and vertically adjustably attached to standards 2!]positioned on the machine frame I. s

The bunch roller 5 and the carriers '8 are driven said apron projectbeyond the front end of the rolling table, transfer means having a pairof cutting edges for cutting off the ends of the cigars, means forperiodically moving said transfer means into a position close beneathsaid part of the apron, expeller members on said transfer 1 .meanshaving substantial extent in the direction transversely of the apron andprovided with rounded portions projecting upwardly beyond said cuttingedges so as to prevent engagement between said cutting edges and saidapron, and means for relatively moving said expeller members and saidpart of the apron to cause said members to sweep off a cigar sticking tothe lower side of said part of the apron. 1

periodically operating the apron to make part of said apron projectbeyond the front end of the rolling table, a pair of cutters havingcutting edges for trimming the ends of the cigars, expelling membershaving rounded surfaces free of said cutters and extending upwardlybeyond said cutters so as to prevent engagement between said cuttersandisaid apron. said membensalsalnaving substantial extent in thedirectionrlaterally ofthe direction of movement of the expeller membersand being arranged at the insides of said cutters and havingbunch-engaging surfaces extending beyond said cutters and between thecutters, means for periodically moving said cutters to position saidexpelling members close beneath said part of said apron, and means forrelatively moving said cutters and said part of the apron to cause saidexpelling members to sweep off a cigar sticking rte tine; lower side ofsaid part of the apron.
